Which Dog Fits Best In A Prominent Family Household Of 6: West Highland White Terrier -or- Toy Poodle?

No offense but does being a “prominent family” mean you have to have a certain type of dog that is “acceptable” to your friends and acquaintances?
It should be what breed of dog best fits your lifestyle and activities. If it is going to be a “see what kind of dog I own” thing, please do not get a dog. They are not commodities or the latest fad. Just because Paris Hilton (or whoever) has a (fill in the breed)___________ dog, doesn’t make it the “thing” to have. Dogs are a lifetime responsibility. Are you prepared for a 10 to 15 year commitment? Vet bills, grooming, boarding if you go out of town? Please do the research on whatever breed you might get to see if the dog matches what you want in a pet/companion.
